Photovoltaics is the technical term for generating electricity from light and
today it is fast becoming an important industrial product. Presently the PV
market is dominated by wafer based crystalline Si cells, but is hampered with
high costs. Today's solar cells are simply not efficient enough and are currently
too expensive to manufacture for large-scale electricity generation. However,
the cost of these cells is likely decrease in the future by using thinner wafers
and devices with higher conversion efficiency. It is here where nanotechnology
is expected to will play an important role in the longer run in order to further
lower the PV cost. PV is also likely to profit from cross fertilization with
micro- and nano-electronics.

Nanotechnologies are worldwide regarded as key technologies for innovations
and technological progress in almost all branches of economy. Nanotechnologies
as key and cross-sectional technologies exhibit the unique potential for decisive
technological breakthroughs in the energy sector, thus making substantial contributions
to sustainable energy supply. In recent years, nanotechnology researchers are
achieving astonishing results in many fields of medicine and electronics: from
microscopic sensors to transistors constantly decreasing in size, industry is
pushing to innovate and find always new, cost-effective solutions. One of the
most promising and exciting progress has been shown in the field of solar cells
development.

The range of possible nanoapplications in the energy sector comprises gradual
short and medium-term improvements for a more efficient use of conventional
and renewable energy sources as well as completely new long-term approaches
for energy recovery and utilization.

Presently, the climate of economic difficulty facing the world is resulting
in a rising demand for going green. An attempt is being made to stimulate economies
by an expansion of government spending in the areas of sustainability, energy
conservation and renewable energy. However the credit crunch and wild swings
in the price of oil could get in the way of these nanotech solutions being aggressively
pursued.

In this scenario, Aruvians Research brings to you its research report - Nanotech:
Making Photovoltaics Possible. This research report takes a look at how nanotechnology
is changing the world of solar photovoltaics and making possible advances which
earlier one could not even possibly imagine. The report looks at the technology
which is making this possible. Basics of nanotechnology, of photovoltaics, of
the current PV industry worldwide, and of course, of the usage of solar power
worldwide, is all analyzed in this report. Information on companies making possible
the usage of nanotechnology to further increase the profitability of photovoltaics
is also provided in this report.

Graphene oxide membranes have been receiving attention for their extremely powerful separation abilities and the ease at which it can be modified, allowing for membrane permittivity to be fine-tuned. These membranes show the potential to be used for water purification, ‘green’ gas purification and greenhouse gas capture.
